Sudden changes of temperature should be avoided. Care should be taken to see that the students do not become chilled by sitting in drafts. It is not safe for the teacher to regulate the heat of the schoolroom by his own feelings. His own good, as well as that of the students, demands that a uniform temperature be maintained.

The brain is the citadel of the being. Wrong physical habits affect the brain and prevent the attainment of that which the students desire—a good mental discipline. Unless the youth are versed in the science of how to care for the body as well as for the mind, they will not be successful students. Study is not the principal cause of breakdown of the mental powers. The main cause is improper diet, irregular meals, a lack of physical exercise, and careless inattention in other respects to the laws of health. When we do all that we can to preserve the health, then we can ask God in faith to bless our efforts.

Before students talk of their attainments in the so-called “higher education,” let them learn to eat and drink to the glory of God and to exercise brain, bone, and muscle in such a way as to fit them for the highest service. A student may devote all his powers to acquiring knowledge, but as he disobeys the laws that govern his being he will weaken his efficiency. By cherishing wrong habits, he loses the power of self-appreciation, and he loses self-control. He cannot reason correctly about matters that concern him most deeply, and becomes reckless and irrational in his treatment of mind and body.
